Abstract

The present invention provides a low-noise plastic intercooler pipe. In preferred embodiments, the present invention preferably provides a low-noise plastic intercooler pipe having a multi-layered structure including: a skin layer including a thermoplastic etherester elastomer (TEEE) and a soundproof core layer including glass bubbles.

Claims

exact text as granted — not AI-modified
1. A low-noise plastic intercooler pipe having a multi-layered structure comprising:
 a skin layer comprising a thermoplastic etherester elastomer; and 
 a soundproof core layer stacked adjacent to the skin layer to form the multilayered structure, the soundproof layer comprising the thermoplastic etherester elastomer, glass bubbles, and a heat stabilizer. 
 
     
     
       2. The low-noise plastic intercooler pipe of  claim 1 , wherein the skin layer and the soundproof core layer are sequentially stacked, and the soundproof core layer is stacked on the skin layer. 
     
     
       3. The low-noise plastic intercooler pipe of  claim 2 , wherein the skin layer and the soundproof core layer are sequentially stacked to form two- to five-layered structures. 
     
     
       4. The low-noise plastic intercooler pipe of  claim 1 , wherein the thermoplastic etherester elastomer contained in the skin layer and the soundproof core layer is a copolymer prepared by copolymerizing 1,4-butanediol, dimethyl terephthalate, and polytetramethylene ethol glycol, and a block copolymer having a structure in which a polyether soft segment and a polyester hard segment are alternately located. 
     
     
       5. The low-noise plastic intercooler pipe of  claim 1 , wherein the thickness of the skin layer is in the range of 0.5 to 1.5 mm, and the thickness of the soundproof core layer is in the range of 1.5 to 3 mm. 
     
     
       6. The low-noise plastic intercooler pipe of  claim 5 , wherein the total thickness of the plastic intercooler pipe is in the range of 2 to 5 mm. 
     
     
       7. The low-noise plastic intercooler pipe of  claim 1 , wherein the soundproof core layer comprises 78 to 95 wt % of the thermoplastic etherester elastomer, 4 to 20 wt % of the glass bubbles, and 0.02 to 2 wt % of the heat stabilizer. 
     
     
       8. The low-noise plastic intercooler pipe of  claim 1 , wherein the heat stabilizer comprises at least one selected from the group consisting of: N,N′-hexane-1,6-diyl bis, 2,2′-m-phenylene bis(2-oxazoline) and 4,4′-bis(a,a-dimethylbenzyl-disphenylamine). 
     
     
       9. The low-noise plastic intercooler pipe of  claim 1 , wherein the plastic intercooler pipe is manufactured using three-dimensional multi-layered blow molding. 
     
     
       10. An automobile comprising the low-noise plastic intercooler pipe of  claim 1 . 
     
     
       11. A low-noise plastic intercooler pipe having a multi-layered structure comprising a skin layer comprising a thermoplastic etherester elastomer; and a soundproof core layer. 
     
     
       12. The low-noise plastic intercooler pipe of  claim 11 , wherein the soundproof core layer comprises the thermoplastic etherester elastomer, glass bubbles, and a heat stabilizer. 
     
     
       13. An automobile comprising the low-noise plastic intercooler pipe of  claim 11 .
